I'm trying to upgrade an OEM version of Windows 7 Professional x64. The key has expired (apparently someone else used it), so we were forced to buy a new full retail edition of Windows 7 Ultimate x64.
I try to do an inplace upgrade, but Windows says I need to use Windows Anytime Upgrade.
So, I've tried this, but I get the following error:
The upgrade key you entered is for an edition of Windows that does not work with Windows Anytime Upgrade.
I'm confused! How do I upgrade to Ultimate if not from a full retail copy of Windows 7 Ultimate??
Doesn't OEM version mean packaged with the PC (like from Dell, HP, etc)? If so, then it doesn't use a manually entered key, but vendor supplied install disk. (to restore just the base professional version). – jdh – 2012-03-07T16:00:02.147
1@jdh - OEM can also mean a system builder OEM disk, which uses license keys like the retail copies. – Shinrai – 2012-03-07T16:00:50.823
